A dutch artist – known only as A. Boogert – created a book of colour in 1692. Describing the use of colour in painting, s/he created an 800-page book with instructions on how to create hues and tones. It blows my mind, actually. The work, the meticulousness, the systematics, and not least: a book like that would not really be possible to reproduce back then. So this tremendous amount of work… for a prototype. I doff my hat to you, A. Boogert. (You can see the entire book here.). Colours are not to be taken lightly. 800 pages seems fitting.
